Nukes would kill everything and anything on the planet, guns kill/injure what they're pointed at. Don't get me wrong, I don't like guns, but nukes to me would be worse.

humans are a detriment to humankind after all who is pulling the trigger or pressing the button?

NUclear weapons are terrorists weapons becasue there is no way they can avoid civilian casualties.

this is like which is worse death or cease of upper brain fuctions

Guns kill people. Nukes kill people, animals, and plants; and they render huge areas of land useless for decades. Nukes are much worse for the future of humanity and the future of life on Earth.

Both, but Nuclear Weapons have brought much worse to the world.

Nukes are worse, because they were brought about to destroy people, and even worse is it was for destruction of whole nations. Guns were first made for survival, making hunting easier.

Nuclear weapons.

For sure Nuclear Weapons.
